Pip重新安装wrin

Question

我一直在处理一个特定的项目（Kivy Buildozer）。我想这没有什么特别的；我认为这是一般性的

安装指南如下所示：

git clone https://github.com/kivy/buildozer
cd buildozer
python setup.py build
sudo pip install -e .

我第一次这样做时，一切都很平静。buildozer可执行文件落在/usr/local/binIIRC中

然后我再次执行此操作，首先删除生成目录：

$ cd
$ git clone https://github.com/kivy/buildozer
$ cd buildozer
$ python setup.py build
$ sudo pip install -e .
Obtaining file:///home/alexey/buildozer
Requirement already satisfied: pexpect in /usr/lib/python3.7/site-packages (from buildozer==0.40.dev0) (4.7.0)

Installing collected packages: buildozer
Found existing installation: buildozer 0.40.dev0
    Uninstalling buildozer-0.40.dev0:
      Successfully uninstalled buildozer-0.40.dev0
  Running setup.py develop for buildozer
Successfully installed buildozer

看起来一切正常，但没有可执行文件：

$ whereis buildozer
buildozer:

$ ls /usr/local/bin/
lightdm-settings  pch  pcp  pcx  prs  radeon-profile  xflock4

这一切有什么错
